WAEC 2024 CHEMISTRY ALTERNATIVE B ANSWERS:
NUMBER 2
Solving/Typing…
====================
NUMBER 3
(3a)
(i)The salt solution was acidic in nature, as it reacted with sodium trioxocarbonate(IV) (sodium carbonate) to produce effervescence and a white precipitate.
(ii)The salt solution contained a calcium or magnesium ion, as these ions form a white precipitate with sodium carbonate.
(iii)The reaction was exothermic, as the test tube became warm, indicating the release of heat energy.
(3b)
(i) PbSO4 (lead(II) sulfate) would not readily dissolve in water, as it is insoluble in water.
(ii) NaHCO3 (sodium hydrogen carbonate) produces effervescence with dilute mineral acids, as it reacts with acids to produce carbon dioxide gas.
(iii) NH4Cl (ammonium chloride) decomposes on heating, as it breaks down into ammonia and hydrogen chloride gases.
(iv) NaHCO3 (sodium hydrogen carbonate) dissolves in water to form an alkaline solution, as it is a basic salt.
(v) NH4Cl (ammonium chloride) sublimes on heating, as it changes directly from a solid to a gas without going through the liquid phase.

2024 WAEC AGRIC SCIENCE PRACTICAL ANSWERS
=======================================
WAEC Agric Science Practical Answers 2024
(1a)
A ranging pole is a robust, often brightly colored pole used primarily in surveying and construction to mark positions and sight lines. Typically, these poles are made from wood or metal, and they are painted in alternating bands of red and white or black and white to ensure high visibility over long distances. Ranging poles usually measure about 2 to 3 meters in length and may be equipped with a pointed end to easily stick them into the ground.
(1b)
(i)Spec A; ranging pole is primarily used to establish sight lines and mark positions on a site during surveying.
(ii)Spec B; An arrow in surveying is a small metal pin that is used to mark positions on the ground where measurements are taken.
(iii) Spec C; A measuring tape is a flexible ruler used to measure distance or size.
(iv)Spec D; A wooden peg is often used to permanently mark the boundaries of surveyed land.
(1c)
Coming!!!!!!
(1d)
(i) Regularly clean the poles after use to remove dirt and mud that can obscure the visibility of the markings.
(ii) Clean arrows of dirt and rust regularly to prevent deterioration.
(iii)After each use, clean the tape by pulling it through a clean rag to remove any dirt, mud, or debris that might have accumulated.
(iv)Before use, ensure that the wooden pegs are dry and free from cracks.
